Iridium-based materials with strong SOC host a variety of exotic quantum phases but also properties of interest for applications [1]}, [2]}, [3]}, [4]}. In IrBiSe, for example bulk electronic bands are split by giant spin orbit splitting about 0.3 eV and are fully spin polarized [5]}. Electronic states in IrBiSe with three-dimensional (3D) chiral spin texture with negative and positive chiralities along crystallographic [111] direction are of interest for spin sensor applications and could exhibit spin-triplet superconductivity upon doping [5]}.
